Also, I don't mind going ahead and doing ECU swaps. If it makes things easier. I'll eventually change a bunch of internal engine stuff after I get the car driving with the new wiring and if the original DA1 computer that I have won't work with this wiring then oh-wellIt's not an easy question to answer because you are using an aftermarket harness. Typically you can use an AOD ecu only with AOD specific wiring. Is there a wiring diagram provided for the harness? part number?
CHeck for voltage on pin 46 with the ecu pulled during key on and cranking. Ensure that you have zero voltage on this pin coming from the harness. (unsure if you tested this). However the aftermarket harness may not even be wired like this so it may not be a concern at all and a lot of these suggestions don't apply.
